3-Phase AC Box - 12-18KVA - 32A - for CONSUEL NFC15-100 - Technideal

Obtain CONSUEL favorable opinion. Mandatory box since 09/01/2025 for CONSUEL inspections (new NF C 15-100 standard) when a generator is connected upstream of the consumption installation.

Case n°1: installation outside the main panel to ensure the protection of the existing installation.

⚡ Who is this box for?

Self-consumption PV installations with a three-phase electricity supply contract ≤ 18kVA.

New construction sites or modifications requiring a new CONSUEL.

Connection of the generator upstream of the protection devices of a terminal circuit (§ 551.7 / § 551.7.2).

⚡ How does the 12-18kVA 3-phase AC upstream box work?

• Connect the inverter output to the upstream box.
• Protect the production with a 4P 32A circuit breaker (12-18kVA at 230 V).
• Respect the rule: In_protection ≤ Ir_AGCP; size S1 at least in accordance with In_protection.
• Inject from the box to the upstream entry point of the consumption installation, without passing through a terminal circuit.
• Declare Case n°1 in your CONSUEL space on the day of the inspection.

⚡ Key points to remember

Mandatory CONSUEL – application from 09/01/2025 (NF C 15-100).

Case n°1: independent box, outside the consumption panel.

Rating: 32A for 12-18kVA three-phase.

Compliance: In_protection ≤ Ir_AGCP; S1 ≥ section required by In_protection.

Prohibition: no connection to a terminal circuit.

⚡ Essential content / equipment

4P 32A thermal-magnetic circuit breaker (12-18kVA, 230 V).

Double 35 mm² terminals (input / output) for a clean incoming-outgoing connection with large sections (AGCP ↔ box ↔ S1 connection).

Case n°1 markings + simplified diagram on instructions/cover.

⚡ Implementation (best practices)

Place the box as close as possible to the AGCP, upstream of the main panel.

Check the Ir of the AGCP and confirm that 32A ≤ Ir_AGCP.

Size the S1 connection according to In_protection.

Prepare the technical file for Case n°1 (CONSUEL platform).
